(snipped for relevance)
I don't see exchanges, devs and users complaining how flawed Segwit it, nobody lost money ore saw critical errors. I only see that bullshit in the Bcash camp.
Can you provide me technical arguments/proof why Segwit is 'flawed' ore show it at the Github?
Yes. Fungibility.
What's the issue with fungibility that's so specific to segwit?
Reliance on miners not to revert to 'anyonecanspend' - an incentive for which only increases over time.
That is, reliance on miners not to try a 51% attack. Does this imply the chain without segwit is invulnerable to 51% attacks?
Besides, any such attack would appear as a fork, which the non-mining nodes would be free to follow or disregard. No substantial change from the pre-segwit state of things, I would say.
A new ability for miners to fail to validate all portions of blocks.
You mean miners running pre-segwit software that have to skip SW transactions?
The list goes on.
How?
